Anatomy: The Lake Trout is torpedo-shaped and has a deeply-forked tail. It has a large head with well-developed teeth on the jaws, tongue, and the roof of mouth. The Lake Trout grows to be about 50 inches (1.25 m), but is usually 17 to 27 inches (43-68 cm). Most weigh from 3 to 9 pounds (1.3-4 kg), but it can weigh up to 120 pounds (55 kg).
The lateral line is a sense organ in aquatic organisms (chiefly fish), used to detect movement and vibration in the surrounding water.
The fins are the most distinctive features of a fish, composed of bony spines protruding from the body with skin covering them and joining them together, either in a webbed fashion, as seen in mostbony fish, or more similar to a flipper, as seen in sharks. These usually serve as a means for the fish to swim. Fins can also be used for gliding or crawling, as seen in the flying fish and frogfish. Fins located in different places on the fish serve different purposes, such as moving forward, turning, and keeping an upright position.
The Dorsal Fin - The main purpose of the dorsal fin is to stabilize the animal against rolling and to assist in sudden turns.
The caudal fin is the tail fin, located at the end of the fish and is used for propulsion and steering.
The anal fin is located on the ventral surface behind the anus. This fin is used to stabilize the fish while swimming.
The paired pectoral fins are located on each side that assists some fish in maintaining depth and helps with steering.
The paired pelvic or ventral fins are located ventrally below the pectoral fins assists the fish in going up or down through the water, turning sharply, and stopping quickly.
The adipose fin is a soft, fleshy fin found on the back behind the dorsal fin and just forward of the caudal fin.
